I just had my first Leopard problem. You guys might have already had this same thing but I wanted to know if you have or not. I was working on Firefox and decided to put my MBP to sleep by closing the screen. I assumed that it was OK to do this without closing Firefox first. Now when I opened the screen again the keyboard did not work. None of the keys did anything. I eventually shut her down and restarted and all was fine. Did I do something wrong by not quitting all the programs prior to putting the computer to sleep?
